| Abstract:: |
| Objective To compare the accuracy of 125I seeds longitudinal distance between groups by degradable catheters and hand. Methods The study was divided into two groups (implantation by degradable catheters and that by hand). There were 12 simulated lesions in each group. Seed needle and 125I seeds were implanted by three physicians according to the set longitudinal distance (0.5 and 1.0 cm). Postoperative CT was conducted and the longitudinal distance between seeds was measured, and then the data was analyzed between the actual distance and the designed distance in each group. Results The degree of deviation from the set distance were (0.184±0.047) and (0.127±0.051) cm in the group by hand, and (0.007±0.006) and (-0.003±0.006) cm in degradable catheters group. The degree of deviation of the seeds in the catheter group was significantly lower than the group by hand (t=3.804, 2.499, P<0.05). Conclusions The accuracy of the longitudinal distance of the group by catheter is much better than that by hand. |
